Sulfasalazine

2-hydroxy-5-[(E)-2-{4-[(pyridin-2-yl)sulfamoyl]phenyl}diazen-1-yl]benzoic acid

C18H14N4O5S (398.0685)

Sulfasalazine is only found in individuals that have used or taken this drug. It is a drug that is used in the management of inflammatory bowel diseases. Its activity is generally considered to lie in its metabolic breakdown product, 5-aminosalicylic acid (see mesalamine) released in the colon. (From Martindale, The Extra Pharmacopoeia, 30th ed, p907)The mode of action of Sulfasalazine or its metabolites, 5-aminosalicylic acid (5-ASA) and sulfapyridine (SP), is still under investigation, but may be related to the anti-inflammatory and/or immunomodulatory properties that have been observed in animal and in vitro models, to its affinity for connective tissue, and/or to the relatively high concentration it reaches in serous fluids, the liver and intestinal walls, as demonstrated in autoradiographic studies in animals. In ulcerative colitis, clinical studies utilizing rectal administration of Sulfasalazine, SP and 5-ASA have indicated that the major therapeutic action may reside in the 5-ASA moiety. The relative contribution of the parent drug and the major metabolites in rheumatoid arthritis is unknown.

S-adenosyl-4-methylthio-2-oxobutanoate

{[(2S,3S,4R,5R)-5-(6-amino-9H-purin-9-yl)-3,4-dihydroxytetrahydrofuran-2-yl]methyl}(3-carboxy-3-oxopropyl)methylsulphonium

C15H20N5O6S+ (398.1134)

S-adenosyl-4-methylthio-2-oxobutanoic acid is a member of the class of compounds known as 5-deoxy-5-thionucleosides. 5-deoxy-5-thionucleosides are 5-deoxyribonucleosides in which the ribose is thio-substituted at the 5position by a S-alkyl group. S-adenosyl-4-methylthio-2-oxobutanoic acid is practically insoluble (in water) and a moderately acidic compound (based on its pKa). S-adenosyl-4-methylthio-2-oxobutanoic acid can be found in a number of food items such as hard wheat, chinese cabbage, cauliflower, and kai-lan, which makes S-adenosyl-4-methylthio-2-oxobutanoic acid a potential biomarker for the consumption of these food products. S-adenosyl-4-methylthio-2-oxobutanoic acid exists in E.coli (prokaryote) and yeast (eukaryote).
